The sibling HTTP::Session::Store::Memcached rejects ids that contain control characters, but the CHI store has no such check, and CHI does not escape keys for its memcached drivers.\n\nWith a memcached driver, a CR and LF in the session id end the cache command early, and the server reads the bytes after them as further commands.","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":["CWE-93"],"vendors":[],"products":[],"references":[{"url":"https://github.com/tokuhirom/http-session/commit/58288cbf941da6d2aad4ff5c0c79e523d9e583b4.patch","tags":[]},{"url":"https://metacpan.org/release/KTAT/http-session-0.53/source/lib/HTTP/Session/Store/CHI.pm","tags":[]},{"url":"https://metacpan.org/release/TOKUHIROM/http-session-0.54/changes","tags":[]},{"url":"http://www.openwall.com/lists/oss-security/2026/11/01/2","tags":[]}],"exploitRefs":[{"url":"https://github.com/tokuhirom/http-session/commit/58288cbf941da6d2aad4ff5c0c79e523d9e583b4.patch","tags":[]}],"hasPoc":true,"ai":null}
